Lightning rods and telephone dedicated grounding wire
(Dangerous during lightning)
Do not touch the power plug or power outlet with wet hands.
Failure to do so can result in electric shock.
Use a single power outlet (do not share a power outlet with
other plugs).
Use an unshared power outlet with an attached ground terminal.
Using the same power outlet together with the power plug of other
devices can result in abnormal heat generation and possible fire.
Firmly insert the power plug into the power outlet.
Be sure to fully insert the power plug into the power outlet until
reaching the base of the plug.
Failure to fully insert the plug or similar fault can result in a short circuit
or heat generation that causes a fire.

Patient weight limit[440 lbs (200 kg)].
The seat may rise slowly if a person weighs close to the chair lift
capacity limit.
Shockless Mechanism
This product is equipped with a shockless mechanism, that allows
smooth starting/stopping chair movement.
This mechanism reduces chair vibrations, enabling smooth chair
operation.
To utilize this mechanism, pay attention to the following precaution;
Chair Preheating Function
Due to the product's hydraulic system and shockless mechanism, the
chair stopping position may slightly vary depending on the oil
temperature and patient weight.
The oil temperature will drop especially during winter season in the
mornings,creating a scatter in the chair stopping position.
When the oil temperature significantly drops, the chair preheating
function will operate for 3 minutes immediately after the product's
main switch is turned on.
The warning sound will beep during this operation.
To cancel the chair preheating function, press any manual chair
movement switch or preset switch.
